Overview

A scheduling reference build covering the cases that make booking systems hard: overlapping resources, time zones, holds, no-shows and rescheduling.

Demo record — an internal reference build, not a client engagement.
Synthetic calendars and reservations only.

The problem

Simple booking tools break as soon as a business has multiple staff, resources or locations — double bookings appear and cancellation rules become inconsistent.

The solution

A booking engine where availability is derived from resource calendars, holds expire automatically, and every state change goes through one validated transition path. Reminders and cancellation rules are configured rather than hard-coded.

Key features

Resource and staff availability modelling
Slot holds with automatic expiry
Time-zone-aware booking and display
Reminder scheduling and cancellations
Admin calendar with conflict warnings
